Uefa president Michel Platini wants to change the transfer window system after claiming it is 'wrong' for a player to represent two clubs in the same season.
Clubs are currently allowed to officially make signings for two months during the summer and also for the month of January.
However, Platini believes the summer window should be made shorter and is keen to assess potential changes to the current system.
"I think we need to get the Uefa strategic committee to look at the whole idea," said Platini.
"I think that it is wrong that a player can play for two clubs in any competition, scoring a goal for one team one week and then scoring against them a few weeks later.
"I also think we have to look at both the summer and winter transfer windows.
"The season starts in many countries in July or early in August, yet the transfer window does not close until the end of August.
"Then we have another window in the middle of the season. I think we need to look at the way the system works."
